| ""Supplementation of flaxseed flour, a source of omega-3 fatty acids for 2 weeks"" Flaxseed in fact has only a precursor to omega3 which the body converts to it. In some peoplewith Inflammation it is thought not to be effectively converted. Fish oil and animal flesh also contain it in the full omega3 form without conversion. Jesus ate a mediterranean diet. |

| "Supplementation of flaxseed flour, a source of omega-3 fatty acids for 2 weeks" Systemic inflammation in morbidly obese subjects: response to oral supplementation with alpha-linolenic acid Alternative Medicine Review, Sept, 2007 by J. Faintuch, L.M. Horie, H.V. Barbeiro BACKGROUND: Morbidly obese patients frequently display asymptomatic chronic activation of acute phase response, with potentially adverse metabolic and cardiovascular consequences. Nutritional preparations to improve this phenomenon have rarely been administered. Aiming to investigate the supplementation of flaxseed flour, a source of omega-3 fatty acids, a prospective randomized double-blind cross-over study was designed. METHODS: Outpatient obese subjects (n = 41) were clinically and biochemically screened, and results for 24 randomized subjects are shown. Age was 40.8 +/- 11.6 years (83.3% females) and body mass index (BMI) was 47.1 +/- 7.2 kg/ [m.sup.2]. Flaxseed flour (Farinha de Linhaca Dourada LinoLive, Cisbra, Brazil) in the amount of 30 g/day (5 g of alphalinolenic acid - omega-3) and an equal mass of placebo (manioc flour) were administered for 2 weeks each. Variables included general biochemical investigation, white blood cell count (WBC), C-reactive protein (CRP), serum amyloid A (SAA) and fibronectin. RESULTS: No intolerance was registered. Body weight and general biochemical indices remained stable. Initial CRP and SAA were elevated (13.7 +/- 9.9 and 17.4 +/- 8.0 ).WBC (8100 +/- 2100/[mm.sup.3]) and fibronectin (463.2 +/- 61.3 mg/dL) were acceptable but in the upper normal range. Corresponding findings after supplementation of flaxseed were 10.6 +/- 6.2 mg/L, 14.3 +/- 9.2 mg/L, 7300 +/- 1800/[mm.sup.3] and 412.8 +/- 38.6 respectively (P<0.05). No change during the control period regarding baseline occurred when placebo was randomized to be given first; however, when it followed omega-3 supplementation, CRP and SAA recovered, whereas WBC and fibronection remained depressed during those 2 weeks (7500 +/- 2100/[mm.sup.3] and 393.2 +/- 75.8 mg/dL, P<0.05). CONCLUSIONS: 1) Various inflammatory markers were elevated in the studied population, although not necessarily exceeding the normal range; 2) Significant reduction could be demonstrated; 3) Some persistent effects of flaxseed supplement 2 weeks after discontinuation were observed. ------------------------------------------------- Different fatty acid intakes results in different fatty acid .. contents.

Links Dietary alpha-linolenic acid increases TNF-alpha, and decreases IL-6, IL-10 in response to LPS: effects of sesamin on the delta-5 desaturation of omega6 and omega3 fatty acids in mice. Chavali SR, Zhong WW, Forse RA. Department of Surgery, Harvard Institute of Medicine, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, MA 02215, USA. Sesamin (a non-fat portion of sesame seed oil) inhibits delta-5 desaturase activity resulting in an accumulation of dihomo-gamma- linolenic acid (DGLA) which can displace arachidonic acid (AA) and decrease the formation of pro-inflammatory mediators. We investigated the effects of consumption of diets containing 0.25wt% sesamin and 15 wt% safflower oil (SO) (providing 12% of the added fat as linoleic acid) or a 15 wt% 2:1 mixture of linseed oil and SO (LOSO) (providing 6% alpha-linolenic acid and 6% linoleic acid) for 3 weeks on the liver membrane fatty acid composition and on the production of prostaglandin (PG) E2, TNF-alpha, IL-6 and IL10 in mice. Consumption of sesamin- supplemented SO and LOSO diets resulted in a significant increase in the levels of 20:3omega6 (DGLA), suggesting that sesamin inhibited delta-5 desaturation of omega6 fatty acids. In animals fed LOSO diets, the levels of alpha-linolenic acid, eicosapentaenoic acid (EPA) and of docosahexaenoic acid (DHA) were elevated with a concomitant decrease of arachidonic acid (AA) in the liver membrane phospholipids. Further, in animals fed LOSO diets with or without sesamin, an increase in the circulating levels of TNF-alpha was associated with a concomitant decrease in PGE2. Despite a lack of differences in the levels of AA, the PGE2 levels were significantly lower in mice fed sesamin- supplemented SO compared to those fed SO alone. Thus, these data suggest that irrespective of the availability of a specific fatty acid as a substrate, through regulating the PGE2 synthesis, the production of TNF-alpha could be modulated.
